  "message": "[Clang] fix crash when constexpr evaluation encounters uninitialized GCC vector (#180293)\n\nFixes #180044\n\n---\n\nThis patch addresses the regression caused by\nhttps://github.com/llvm/llvm-project/commit/77534291fcbd2c784c54e39a60895e4f60f19742.\nThe crash happens because\n\n\nhttps://github.com/llvm/llvm-project/blob/85d94e17144f2ca250c91b827b59e6ddea675d31/clang/lib/AST/ExprConstant.cpp#L4294\n\ntries to read a vector element when the `APValue` is still\n`Indeterminate` or `Absent`. These changes _populate_ vector `APValue`\nto ensure elements exist before access.",
